James (11H Randall Watented Aug. 11, 1931 STATES JAMES W. E. RANDALL, @FNEW YORK, H. Y SSIGNOB: TGILIBBEY-QWMtfi-EQRD G COMPANY, OF TOLEDO,OHIO, A CORPORATION OF ail.

Application filed February 24, 1828. Serial No. $56,585.

The present invention relates to aprocess and apparatus iior sealinglaminated glass. An important. object of the invention is to provide aprocess and apparatus for scaling s lim-inatedglass wherein liquidsealing materialis fed into a groove in the laminated sheet by means ofan electrically heatedimplement.

Another object of-the invention is to prose vide a. process and;apparatus for sealing laminatedv glass wherein acontainer'for thesealing medium and the sealing implement are movable as unit, thesealing medium being adapted tobe fed into the groove in is which theseal is to-be formed by means of an electrically heated member.

Other objects and advantages of the invention willbecome more apparentduring the course'ot the following description.

In the drawings wherein like numerals are employed to designate likeparts throughout the same,

Fig. 1 isa perspective view, partly in section, illustratin a sheet oflaminated glass at before the seal as been applied,

Fl 2 is a diagrammatic view illustrat- 111%} e sealing of the laminatedsheet, andig. 3 is a perspective view, partly in section, illustrating afinished sheet. of, laminated' glass including the seal.

Reterring toFi 1, the numeralslO and 11 desate two s sets of preferablytransparent glass whose surfaces may be ground and polishe ,ornot, asdesired. Interposed between the glass sheets and united, thereto is anon-brittle sheet 12 which is 'oined to the glass sheets by means of ana esive or the like 13. This. invention is not limited to any particulartype of laminated glass, the materials used: in its structure, or theprocess of laminating.

As she in=Fig. 1, the sheet of laminated glass has a channel; orgrooveltwhich is provided to receive the sealing medium.

in Fig. 2, the numeral 15 designates the sealing machine which comprisesa receptacle adapted to contain the sealing material which may be ansuitable resin, varnish,

itch, waxes, or t e like. The sealing meso i is preferably in a liquidor semi-liquid the sealin condition and is adapted to be mantained inthis condition by means of an electrical heater arranged preferablyaround the receptacle and deriving current from the conduit 16. Anysuitable form of rheostat or 55 thelike may be used to control theamount of current passing through the heater whereby to control thetemperature and fluidity or viscosity of the sealing medium. Arrangedpreferably in the bottom of the reso ceptacle containing the sealingmedium is an outlet 17 controlled by means of a valve or the like 18. Aflow of sealing material 19 is adapted to issue from the conduit 17.

To deposit the sealing material 19 in the 65 channel 14, a preferablywire worm'ng end 20 is carried by the device 15. The member 20 ispreferably formed from a nickel chrome wire which is adapted to beheated by current supplied through the cable 21, to

or if. desired the cable16 may also be used to supply the necessarycurrent tothe working end 20. In any event, it is desirable to provide aseparate control means for the member 20 and the receptacle containingthe 75 sea' material. The wire 20 is so arrange with respect to theoutlet conduit 1?! that the sealing medium 19 flows directly thereon.Handle means 22 and 23 respectively are provided to hold and operate theno device 15, and todeposit the sealing material in the channel 14 thevalve 18 is properl adjusted topermit the flow of sealing med ium topass downwardly as illustrated in Fig. 2. By moving the device 15 withthe as wire 20 in the groove 14, it will be seen that material will befed within the roove. pon cooling,the seal 24, shown in ig. 3, willresult. The seal 24: will provide an eflicient protecting means for theso laminated sheet.

It is to be understood that the form or the. invention herewith shownand described is to be taken as the preferred ement of the same, andthat various changes inrthe 9e shape, size and arrangement of parts maybe resorted to without departing from the spirit of the invention or thescope of the subjoined claims.
